Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP, the currency of energy in cells.
The formula for cellular respiration is C6H12O6+O2=CO2+H2O+ENERGY. Therefore, by definition, cellular respiration is the process within cells by which cells convert sugar and oxygen to energy, with water and carbon dioxide as the waste products. Without oxygen, this process simply cannot take place.
